Izinyathelo zokuqinisekisa ikhwalithi yokushisela zihlanganisa:
1. Izici zobuntu ziyizinto ezibalulekile ekugxilwe kuzo ekulawuleni ukushisela kwamapayipi kathayela. Ngenxa yokuntuleka kwezindlela ezidingekayo zokulawula i-post-welding, kulula ukusika amakhona, okuthinta ikhwalithi; ngesikhathi esifanayo, uhlobo olukhethekile lwe-welding yamapayipi e-galvanized yenza kube nzima ukuqinisekisa ikhwalithi yokushisela. Ngakho-ke, ngaphambi kokuthi iphrojekthi iqale, kufanele kukhethwe umshicileli ochwepheshile ophethe umkhumbi we-boiler ofanele noma isitifiketi esilinganayo sokushisela kufanele kukhethwe. Ukuqeqeshwa okudingekayo kwezobuchwepheshe kanye nemiyalelo kufanele kuhlinzekwe, futhi ukuhlolwa kwe-welding endaweni kanye nokugunyazwa kufanele kwenziwe ngokusekelwe ezimweni zokubhayela. Imithetho yokuhlolwa kwe-pressure welding welding kufanele ilandelwe. Ukuguqulwa okungagunyaziwe akuvunyelwe ukuze kuqinisekiswe ukuzinza okulinganiselwe kwabasebenzi bokushisela ekushiseleleni amapayipi.
2. Ukulawulwa kwezinto zokushisela: Qinisekisa ukuthi izinto zokushisela ezithengiwe zitholwa eziteshini ezinedumela elihle, ziphelezelwa izitifiketi zekhwalithi nemibiko yokuhlolwa, futhi zithobelana nezidingo zenqubo; ukwamukelwa, ukuhlunga, kanye nezinqubo zokusabalalisa izinto zokushisela kufanele zifane futhi ziphelele. Ukusetshenziswa: Izinto zokushisela kumele zibhakwe ngokuqinile ngokwezidingo zenqubo, futhi ukusetshenziswa kwezinto zokushisela akumele kudlule isigamu sosuku.
3. Imishini yokushisela: Imishini yokushisela ingamathuluzi okushisela futhi kufanele iqinisekise ukusebenza okuthembekile nokuhambisana nezidingo zenqubo; imishini yokushisela kufanele ifakwe ama-ammeter afanelekayo kanye nama-voltmeters ukuqinisekisa ukuqaliswa okufanele kwenqubo yokushisela. Izintambo zokushisela akufanele zibe zinde ngokweqile; uma kusetshenziswa izintambo ezinde, imingcele yokushisela kufanele ilungiswe ngokufanele.
4. Izindlela Zenqubo Yokushisela: Bambelela ngokuqinile ezinkambisweni ezikhethekile zokusebenza zamapayipi anamathani. Yenza ukuhlolwa kwe-bevel pre-welding ngokuya ngenqubo yokushisela, lawula imingcele yenqubo yokushisela nezindlela zokusebenza, hlola ukubukeka kwekhwalithi yangemuva kokushisela, futhi wenze ukuhlolwa okungabhubhisi njengoba kudingekile ngemva kokushisela. Lawula ikhwalithi yokushisela yephasi ngayinye kanye nenani lezinto ezisetshenziswayo zokushisela.
5. Ukulawulwa Kwendawo yokushisela: Qinisekisa ukuthi izinga lokushisa, umswakama, nesivinini somoya ngesikhathi sokushisela kuhambisana nezidingo zenqubo. Ukushisela akuvunyelwe ngaphansi kwezimo ezingafanele.
